Ford super duty 3.31 rear end. Will it be a big mistake. ?
Pulling a 37 foot Cedar creek with a f350. Diesel. Would the 3.31 rear end work or should I get the 3.55?

I've been towing with the 3.31 rear end since 2012 - coupled with the six speed tranny it's perfect - flat land or mountains makes no difference.
